Product details
Overview
PDTA114EU from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, rated for −50 V VCEO, −100 mA output current, with integrated R1 = 10 kΩ and R2 = 10 kΩ bias resistors; used as a digital switch for IC input control and load switching in automotive and industrial modules.
For engineers reviewing the PDTA114EU datasheet, PDTA114EU pinout, PDTA114EU application, or PDTA114EU equivalent, key selection criteria include its built-in resistor ratio (R2/R1 = 1), guaranteed VI(on) ≤ −1.8 V at −10 mA, and thermal resistance of 625 K/W on FR4 PCB - critical for compact, high-reliability digital interface designs.
Technical Context
This PNP RET integrates two precision bias resistors directly into the die assembly, eliminating external base resistors and enabling direct logic-level drive from microcontrollers or gate drivers. Its simplified three-terminal structure (Input/Base, Ground/Emitter, Output/Collector) replaces discrete BJT + dual-resistor configurations.
The device operates with guaranteed DC current gain (hFE) ≥30 at −5 mA collector current and −5 V VCE, while maintaining low VCE(sat) ≤ −150 mV at −10 mA IC and −0.5 mA IB, ensuring efficient switching in low-voltage digital systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage under open-base condition; supports 24 V industrial bus interfacing with margin. |
| IO | −100 mA: Continuous output current rating; sufficient to drive LED indicators, small relays, or logic inputs. |
| R1 | 10 kΩ ±30%: Integrated input bias resistor; sets base current for predictable turn-on without external components. |
| R2/R1 | 1.0 ±0.2: Matched internal resistor ratio; ensures stable saturation and consistent switching thresholds across temperature. |
| VCE(sat) | ≤ −150 mV at IC = −10 mA: Low saturation voltage minimizes power loss and heat generation in active switching state. |
| hFE | ≥30 at VCE = −5 V, IC = −5 mA: Minimum DC current gain guarantees reliable amplification in linear or saturated switching modes. |
| Ptot | 200 mW at Tamb ≤ 25 °C: Total power dissipation limit on standard FR4 PCB; derates linearly above 25 °C per Fig. 1. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body size, 1.3 mm lead pitch, optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (Base) | Connected internally to R1; accepts TTL/CMOS logic-level signals to enable transistor conduction. |
| 2 | Ground (Emitter) | Common reference node; ties emitter to system ground, completing bias path through R2. |
| 3 | Output (Collector) | Switched high-side output node; sinks current from load to ground when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched R1 = R2 = 10 kΩ eliminates need for two external resistors, reducing BOM count by 2 parts. |
| Reduced pick-and-place cost | Single-component replacement for BJT + dual-resistor subcircuit lowers SMT placement time and feeder usage. |
| Guaranteed VI(on) | ≤ −1.8 V at IC = −10 mA ensures compatibility with 3.3 V and 5 V logic families without level-shifting. |
| Thermal robustness | Rth(j-a) = 625 K/W on standard FR4 enables operation up to 125 °C ambient with proper layout. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door module PCBs. IC Role / Device Role: Digital interface switch translating MCU GPIO outputs to higher-current loads. Use Value: Eliminates discrete resistor placement and reduces footprint by >40% vs. BC847 + 2× 10 kΩ solution. |
Use Scenario: Conditioning 24 V field sensor signals before feeding to isolation amplifier inputs. IC Role / Device Role: Level-shifting and current-limiting interface between industrial sensors and analog front-end. Use Value: Built-in resistor matching ensures stable threshold behavior across −40 °C to +100 °C operating range. |
| Consumer Appliance Control Board | Medical Diagnostic Equipment Interface |
Use Scenario: Enabling/disabling buzzer and display backlight circuits in smart oven controllers. IC Role / Device Role: Low-power load switch controlled directly by 3.3 V microcontroller pins. Use Value: VI(on) ≤ −1.8 V allows full saturation using 3.3 V logic without external pull-up or driver stage. |
Use Scenario: Isolating microcontroller I/O lines from relay-driven actuator circuits in patient-monitoring devices. IC Role / Device Role: Safe, low-leakage digital isolator for safety-critical signal paths. Use Value: ICEO ≤ −5 µA at 150 °C junction temperature ensures minimal false triggering during thermal stress testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EU | NPN complement with identical R1/R2 values and package; VCEO = +50 V, IO = +100 mA. | Requires inverted logic drive and high-side load configuration instead of low-side sinking. | Select when sourcing current from VCC is preferred over sinking to GND. |
| BC807-40 | Standard PNP BJT without integrated resistors; hFE = 250–630, VCEO = −45 V, requires external R1/R2. | Higher gain but adds 2 passive components and layout area; less predictable turn-on threshold. | Choose only if variable bias or higher hFE is required and board space permits extra passives. |
Compared with PDTC114EU, the NPN version demands reversed signal polarity and load topology; versus BC807-40, PDTA114EU trades raw gain for design simplicity, repeatability, and reduced assembly cost - making it optimal for fixed-ratio, high-volume digital switching.

FAQ
What is the maximum allowable input voltage at Pin 1 (Input/Base)?
The absolute maximum input voltage is −40 V, but the functional operating range is −10 V to 0 V. VI(off) is specified as ≤ −0.8 V (typical −1.1 V), meaning the device reliably stays off when input is pulled above −0.8 V. Exceeding −10 V risks exceeding the VEBO limit of −10 V and may damage the internal E-B junction.
Can PDTA114EU be used in linear amplification mode?
No - this device is optimized for digital switching, not analog amplification. Its hFE is only guaranteed ≥30 at IC = −5 mA, and no linearity, frequency response, or distortion data is provided. The integrated resistors fix the bias point, preventing adjustable Q-point setting required for linear operation.
Is the R1/R2 ratio matched across production lots?
Yes - the datasheet specifies R2/R1 = 1.0 ±0.2 (0.8 to 1.2) under defined test conditions, and Nexperia's RET process controls resistor tracking within this tolerance band across temperature and lot-to-lot variation, ensuring consistent VI(on) and saturation behavior.
Does PDTA114EU meet automotive qualification standards?
No - the datasheet explicitly states this part is "non-automotive qualified" and has not been tested to AEC-Q101. It is intended for industrial and consumer applications; use in automotive systems requires customer validation and assumes full liability, as stated in Nexperia's legal disclaimers.
